4 Claims. 1

This invention relates to support devices, and more particularly supports adapted to be temporarily fastened, such as to an article of furniture, as a table, etc.; and among the features of the invention are the provision of structure'to adjustably fasten onto different forms of available edges, and the, provision of structure for holding a range of articles. Other objects and advantages will appear from the following description.

To the accomplishment of the foregoing and related ends, the invention, then, comprises the features hereinafter fully described and particularly pointed out in the claims, the following description setting forth in detail certain illustrative embodiments of the invention, these being indicative, however, of but a few ofthe various ways in which the principle of the invention may be employed.

In said annexed drawing:

Fig. l is a perspective view of an embodiment of the invention, in one arrangement of attachment; v

Fig. 2 is a similar view, partly broken, showing another arrangement of attachment;

Fig. 3 is a perspective view of the attaching portion of the tructure;

Fig. 4 is a perspective view of the support arm; and

Fig. 5 is a perspective view of the locking clamp.

In general, the device involves an L-shaped support member adjustably carrying the holder portion for the articles to be'supported, and a generally U-shaped member carrying thei L- shaped member and being fastenable on an available edge of an article. of furniture, as for instance a table. As adapted for fastening to a horizontal edge, as illustrated in. Fig. 1, the'relationship of the generally ,U-shaped member U with the L-shaped member L involves the positioning of the latter with one limb of the L against the web portion of the U member, and for this, the latter at thejuncture of its flange 2 and its web 3 has a rectangular cut-out l, Figs. 1 and 3, through which the one limb 5 of the L-shaped member enters to lie parallel against Web 3, while the end of the limb 5 rests at the juncture of the web 3 and the flange l of the U-member. Here, there is an expanded recess 5 formed at the angle, as shown particularh clearly in Fig. 2; and as shown at Fig. 4 the limb 5 has at its ,end lateral gudgeons 8 which seat in the recess 6. Preferably, the gudgeons are positioned close to the back and end of the limb 5 so as to more particularly seat into the recess 6.

,2 A thumb-screw {l is threaded into the flange l of the U-mem'benand thereby the device may be clamped to a projecting-horizontal edge, as a table. Such edge being in contact against the limb 5 and the whole tightly'se'curedby the thumb screw, displacement of the'relative position of the L-shaped member in the clamping U-membe-r is prevented; but for additional security it is preferred to provide a lock or latch S in the form of a slide, Fig. 5, on the limb 5. This slide, of suitably thick stock has rebentfianges H which extendfrom the main body I-Z 'and partly surround the limb 5, while the lateral arms I3 form a catch or' holding means againstthe Urmember. It is noticed that the juncture of theweb 3 and the in Fig. 1, and additionally hold against relative displacement between the L.-member and the U-member. The other limb I6 of the L-member adjustably carries the holder portion H; 'and while this may vary in its detailed form, a generally useful embodiment involves a trough-like member with walls l8, l9, spaced apart for such articles as are to be accommodated. By suitably folding up proper heavy stock", the holding trough may be closed at the bottom and'provide' desirable all-round rigidity. Where desired, this member may be of arcuate form instead of straight, as shown in Fig.v 1. The endsfof the trough-like member may closed by suitable closure me'ans.- Projecting from the trough-like member is' lug 2! which has an opening through which a holding bolt or screw 21 fastens nane 'to the limb l6. 1 The bolt "or screw" 22fmay be a conveniently large thumb-nutlhead 23,"and most simply this'may' be integral withthe threaded shaft and permit'adjustment and :"ghte ing'into a: threaded opemng l1 in'the u'mb'it. I

In effect, the L-membe'r isarticulatedtoth U-member, and this permitsa ready shiftof relative position such that wher'ethe device is to be" fastened. n o a verticaPedge' f r example-{fa flanged-edge table, the relationship'of the par-ts" is as shown in Fig. 2. The slide S having been loosened and retracted from the position shown in Fig. 1, the U-member is slid along the limb 5, bringing the gudgeons 8 out of the recess 6, and positioning them in the recess 25 which is at the juncture of the flange 2 and web 8 ofjthe U-memher, as shown best in Fig. 3. 'Ihisincludes a. slight deformation outwardly at the juncture, sufiicient to accommodate the gudgeons and end of the limb 5 which rests against the inside of the flange 2 of the U-member as in Fig. 2. Here again, the clamping of the thumb-screw 9 against the flange of the table or the like holds the parts in their position, but for additional securement the slide 5 again can exert a locking function. The flange 2 of the U-nember is provided with two end slots 2?, and in the relative position of the parts as in Fig. 2, it is seen that the slide when pushed down enters the slots 27 with its rebent portions H, the ends of these being on the outside, while the lateral projections l3 slide down on the inside of the flange 2. Thus the limb 5 i positively locked to the flange 2.

All-around applicability to available edges for fastening on, is thus had, and the device is of convenience in holding various articles, illustrated for instance in Fig. l at A.

Other modes of applying the principle of the invention may be employed, change being made as regards the details described, provided the features stated in any of the following claims, or the equivalent of such, be employed.

I therefore particularly point out and distinctly claim as my invention: I

l. A support, comprising a generally U-shaped member adapted to be attached to either horizontal or vertical supporting edges and an L- shaped member connected thereto, said U-shaped member having a clamping thumb-screw in one of its flanges and a recess at the juncture of such flange and the U-member web portion, and a recess and cut-out at the juncture of the web and the other flange, the latter flange having a pair oi end slots-said a-shaped member having one limb passing; through said cut-out and resting againstthe inside of the web portion of the U-member withend at the recess between the weband thethumb-screw flange in one position, and in another position against the outside of the U-member flange having thelend slots, an external ridge at the juncture of the latter flange and web, a lock slide on said L- member engaging the end slots of the U-member flange in one position and'engage behindthe zontal or vertical supporting edges and an L- shaped member connected thereto, said" U- shaped member having a-clamping thumb-screw in; one of its flangesyand-arecess at the juncture of such flange and the U-member web portion,
